Undocumented functions: a digest

[Jeremy White]

Thanks to everyone who sent me examples of undocumented
information; I have passed that along; I think it
will be very helpful.

I was hoping to edit it, and make it a bit more definitive,
but I seem to have run out of time.

So, I thought I'd just post the raw replies here so 
it didn't vanish into the bit bucket.

Cheers,

Jeremy
